C-Axis Properties of DyNi$_{2}$B$_{2}$C System

We have measured the electrical resistivity along c-axis $\rho _{c}$(T, H) of the DyNi$_{2}$B$_{2}$C single crystal with the magnetic fields perpendicular to the c-axis and the magnetization isotherms M(H) of the DyNi$_{2}$B$_{2}$C single crystal with magnetic fields perpendicular and parallel to the c-axis. We confirmed that Neel temperature T$_{N}$ is 10.3K from the $\rho _{c}$(T) result which is consistent with that from previous $\rho _{ab}$(T) result. In addition, the constructed critical fields H$_{c2}$(T) curve and magnetic transitions diagram of DyNi$_{2}$B$_{2}$C from $\rho _{c}$(T) magnetic fields perpendicular to c-axis is similar to that of $\rho _{ab}$(T) result, which is thought to arise that 3 D magnetic structure of DyNi$_{2}$B$_{2}$C.
